Dan, you said you had to make the lift rod. Now it just might be the way it looks in the picture, but to me it looks like the plow is sitting on the ground and the implement lift arm looks straight up and down to the ground. Usually with the implement lowered the arm would be tilted somewhat forward thus you would lean a little forward to grasp it and use more of your back than just your arm to pull back the lever. Maybe the rod you made is just a tad too long. Perhaps others can pipe in an that. As far as the lift spring assist operation, think of it as the spring just aiding in the twisting of the rock shaft that the implement lift handle is connected to, that meaning you aren't doing all the work when you pull back on the handle. The spring doesn't really pull or or lift anything at all.
